Geological factors controlling high flowback rates of shale gas wells in the Changning area of the southern Sichuan Basin, China

Frontiers in Earth Science
In the Changning block of the southern Sichuan Basin, the shale gas wells in the Upper Ordovician Wufeng Formation to Lower Silurian Longmaxi Formation (Wufeng–Longmaxi) demonstrate significant difference in flowback rate of fracturing fluid, given the ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Does Market Competition Reduce Corporate Environmental Investment? Evidence From China's Anti‐Monopoly Law

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether stronger competition supports or constrains corporate environmental responsibility, using China's 2008 Anti‐Monopoly Law as a quasi‐natural experiment. Applying a difference‐in‐differences design to Chinese A‐share listed firms in heavily polluting industries from 2006 to 2019, we find that firms with high ...

Nonlinear Fractal Flow Model of Fractured Vertical Wells With Stimulated Reservoir Volume Considering the Quadratic Gradient Term

Geofluids
Although various fractal flow models have recently been developed to investigate pressure responses of fractured vertical wells, almost all of the existing fractal models ignore the quadratic gradient term (QGT), which makes them violate mass ...

Carbon Coking‐Tolerant Perovskite Catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 for Efficient Methane Dry Reforming

Carbon and Hydrogen, EarlyView.
A new perovskite‐type catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 was developed for methane dry reforming, which exhibited 93.1% CH4 and 94.7% CO2 conversion with 100 h stability run and excellent anti‐coking capability, benefited from in situ exsolved Fe‐Ni alloy nanoparticles. ABSTRACT Perovskite with high temperature stability and tunability is a very promising
